Pav*_*vel 6 php forms checkbox
我有一个关于php表单的问题.我已经在现有表单中添加了一个复选框,但不确定如何将其添加到php.如果访问者检查它,我希望发送"是",如果不是,则发送"否".
<form method="POST" name="contactform" action="contact-form-handler.php">
<p>
<input type="text" name="name" placeholder="name">
</p>
<p>
<input type="tel" name="tel" placeholder="phome"> <br>
</p>
<p>
<input type="text" name="email" placeholder="mail"> <br>
</p>
<p>
<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up for newsletter<br>
</p>
<input type="submit" value="Submit"><br>
</form>
这里是表单的php代码,除了复选框之外的所有内容.我收到邮件时需要知道它的价值.例如:"姓名:约翰,电子邮件:test @ test.com,电话:12345,通讯:是"
<?php
$errors = '';
$myemail = 'test@gmail.com';//<-----Put Your email address here.
if(empty($_POST['name']) ||
empty($_POST['email']) ||
empty($_POST['tel']))
{
$errors .= "\n Error: all fields are required";
}
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
if (!preg_match(
"/^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,3})$/i",
$email_address))
{
$errors .= "\n Error: Invalid email address";
}
if( empty($errors))
{
$to = $myemail;
$email_subject = "Contact form submission: $name";
$email_body = "You have received a new message. ".
" Here are the details:\n Name: $name \n Email: $email_address \n Tel \n $message\n Newsletter \n $newsletter"
}
;
$headers = "From: $myemail\n";
$headers .= "Reply-To: $email_address";
mail($to,$email_subject,$email_body,$headers);
//redirect to the 'thank you' page
header('Location: contact-form-thank-you.html');
}
?>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<head>
<title>Contact form handler</title>

<body>
<!-- This page is displayed only if there is some error -->
<?php
echo nl2br($errors);
?>

这是为了在Yes检查时返回一个简单的内容.
<input type="checkbox" id="newsletter" name="newsletter" value="Yes" checked>
<label for="newsletter">i want to sign up for newsletter</label>
我还将文本添加为标签,这意味着您也可以单击文本以选中该框.小但是,我个人讨厌网站让我把鼠标对准这个小小的复选框.
如果选中该复选框,则提交表单$_POST['newsletter']将相等Yes.只要你是如何检查是否$_POST['name'],$_POST['email']以及$_POST['tel']是空的,你可以这样做.
这是一个如何在php端将其添加到您的电子邮件中的示例:
在现有代码下面:
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
加:
$newsletter = $_POST['newsletter'];
if ($newsletter != 'Yes') {
$newsletter = 'No';
}
如果选中该复选框,则会Yes在您的电子邮件中添加未添加的电子邮件No.

如果选中该复选框,您将在$_POST阵列中获得它的值.如果不是,则元素将完全从数组中省略.
测试它的最简单方法是这样的:
if (isset($_POST['myCheckbox'])) {
$checkBoxValue = "yes";
} else {
$checkBoxValue = "no";
}
对于您的代码,请将其添加到其他预处理的正下方:
$name = $_POST['name'];
$email_address = $_POST['email'];
$message = $_POST['tel'];
if (isset($_POST['newsletter'])) {
$newsletter = "yes";
} else {
$newsletter = "no";
}
您还需要稍微更改HTML.改变这一行:
<input type="checkbox" name="newsletter[]" value="newsletter" checked>i want to sign up for newsletter<br>
对此:
<input type="checkbox" name="newsletter" value="newsletter" checked>i want to sign up for newsletter<br>
^^^ remove square brackets here.
